MEANS FOR. EFFECTING TEMPORARY REPAIRS TO BROKEN AXLES 0F MOTOR-CARS.

To all whom it may concern:

Be it known that I, EDWARD JAMES Dovn, of 190 St. Johns street, Clerkenwell, London, E. C. 1, England, yeast merchant, a subject of the King of Great Britain, have invented certain new and useful Means for Effecting Temporary Repairs to Broken Axles of Motor-Cars, of which the following is a specification.

This invention relates to motor cars of the Ford type, in which the axle casing care ries the .load, and has for its object to provide improved means whereby the driving axle of'such a car, when broken at a point on either side of the differential gear, may

. be easily and quickly repaired either so far as is necessary 1n order to permit of the car being safely towed on its own wheels, or so far as is necessary to enable the car to be driven away by its own power.

For the purpose of ,enablinga car to be towed when either section (right or left hand) of the driving axle of the car is broken, the corresponding wheel is removed, the severed portion of the axle with the attached part of the brake gear is withdrawn, and the roller-bearings are detached from the axle-casing. In placeof the severed portion, of the axle, there is inserted a spindle adapted externally to fit within the axle-casing and internally to fit over the outer end of that portion of the broken axle which remains connected with the differential gear; this spindle, which passes out through the usual brake-drum, having its hold the previously removed wheel in its usual position, while the spindle is pro vided with an annular retaining collar for holding it in proper position relatively to the remaining broken portion of the axle. According to this invention the spindle which is fitted withinthe axle-casing and which is adapted to fit over the outer end of that portion of the broken axle which remains, is provided with a ring adapted to fit closely within the axle casing and mounted on a-ball bearing on the spindle.

Theinvention is illustrated in the accom panying drawings wherein similar references indicate like parts and wherein Figure 1 is a side elevation of one form of spindle, Fig, 2 is a face view and Fig. 3 is a cross section on the line 3 3 Fig. 2 of a detail, Fig. 4; is a sectional elevation on a smaller scale showing the spindle in position for Specification of Letters Patent.

use, Figs. 5 and 6 are respectively a plan and a side elevation of a modified form of spindle, Fig. 7 is a sectional'elevation on a smaller scale showing the modified form of spindle inposition for use and Figs. 8 and 9 are sectional elevations of details.

As shown in Figs. 1 and 4 the spindle a has the middle portion 6 of its length made of a diameter to fit easily within the outer end portion of the axle-:casing 0 while the inner portion cl ofits length is of reduced diameter and hollow as at 0 so as to fit over ed upon a ball bearing m on the middle portion Z; of the spindle is a ring a made of a diameter to fit closely within the outer end portion of the axle-casing a while a collar 0 placed on the spindle at the junction between the middle and @outer portions 5 and of the length of the spindle is also situated within the outer end portion of the axle easing 0 and is furnished with a thrust-ball bearing 9 and against the thrust-ball bearing Q is fitted an. annular retaining collar 1" formed with a ball race 3 and which embraces a circumferential flange 0 of the collar 0; the aperture t in the retaining collar 1", which is preferably rabbetedas at a so as to fit over both the flange 0 and the outer end portion of the axle casing c, is prevented from revolving relatively to the brake drum p by an arm '0 which projects radially from the retaining collar rand has a holew near its extremity whereby the arm 4) may be secured within the brake-drum p by means of a bolt a: passed through said hole to and a corresponding hole presented in the drum 70 in consequence of the removal of the brake.

The spindle a may be tubular throughout be formed with grooves running directly as tures 12 in the other.

each row are spaced apart a distance equal at 3 or helically as at .2 around its periphery,

and one of the grooves y. may. be engagedby the point of a set-pin 1O screwed through the hole presented in the wall of the axle-casing 0' on the detachment of the usual grease cup.

In the modified form of the invention shown in Figs. 5 to 9 the inner port1on (Z of the spindle is prolongedan'd; is formed with four rows of threaded apertures 11, and 12, lying in axial planes intersecting approximately at right angles, the apertures 11 lying in the one axial plane and the aper- The apertures 11 in to twice that intervening between adjacent apertures 12 and while the apertures 11' in both rows are arranged at the points of intersection of two helices, the one right handed and the other left handed the-aper tures 12, are. arranged so that adjacent apertures lie the one in the right handed helix and the other in the left handed helix and a in order that the respective helix to which the apertures 12 appertain maybe readily recognized the inner portion (Z of the spindle is engraved or otherwise marked with right and left'handed helices 15 and 16 respectively. The threadedapertures 11 and 12 are adapted to receive, on the one hand,

grub screws 17 formed'with hardened points adapted to project through to the interior of the portiond and to cut into-the outer end of'the axle 7- whiclr remains on the car, and on the other hand, a grubscrew 18 adapted to projectthrough to the interior end of the spindle approximately equal to the length of said outer portion of the broken shaft, and the grub screws 17 are engaged with threaded apertures 11 at a greater distance from the outer end of the spindle and with threaded apertures 12,

which lie in the right handed or left handed helix according asthe broken axle is on the left or right hand side of the car respec' ti'vely. Preferably the grub screws 17 are engaged with the apertures 11 and 12 so as to project successively greater distances into the inner portion (5 from the inner part of'the latter toward the outer part thereof, The spindle is then slidden into position so that the portion (5 receives into itthe outer end of the broken axle f and the spindle is V rotated to the right or left as thecase may be soas to-cause the hardened points of the grub-screws17 to bite into said axle. This rotation of the spindle causes a screw thread to-becut in the axle as shown in Figs. 8 and 9, thethread being started atseparate points and, ultimately jolIl'l'Ilg ilpj to constitute a single thread. i The length of the screw thread so formed isdetermined by the grub screw' 18 which not only prevents further' rotation ofthespin dle when thedesired length of threadhas been cut but preyents relative endwise movement of the spindle and the axle f when power is applied through axle/casing and a Vbrake-drum thereon, said means comprising a spindle having one end hollow and adapted externally to fit within the axle casing and internally'tofit over that ortion of the broken axle which remains the outer endrof said spindle being adapted to receive and hold in position a wheel, and

said spindle being provided with means adapted to holdsaid'spindle in proper posi-' tion relatively to the remaining broken portion of the axle, a ring adapted to-fit' closely in sa1d-axle casing, anda ball-bearing 1nsald ring, sa1d spindle being adapted to revolve in said ball 'b'earing.
